Now, my memories about the game are not very clear but I do remember some problems with a safe whose code I knew.

I remember having to figure out by trial and error how old safes actually worked, I just accepted it as part of the game. Though I might be thinking on a different one, I seem to remember it being inside a shop or something.

If you’re really stuck you can always try any walkthrough on the net, it doesn’t make you any less of a man to look one or two once in a while.
